To make it complete, here is the code that I am using to encode a large file: int __stdcall SpxEncode(unsigned char* inBuf, unsigned char* outBuf, unsigned int inlen) { //char *testFile; //FILE *ftest; //testFile = "test"; //ftest = fopen(testFile, "wb"); //fwrite(inBuf,1,inlen,ftest); //take every 320 bytes //copy every short to float

Hello, I have a vector (numeric) v-> c(a,b,c,d,e) and I want to create the vector n->c(b-a,c-b,d-c,e-d). How can I do that? Thank you Hermann [[alternative HTML version deleted]]

Dear list, I wish to plot chromatin precipitation data: I would like to have a rectangles (x:end-start, y:peak) but I do not have an idea how to define x (in terms of qplot syntax) and to choose the correct geom. mydata is a subset of a larger file. > mydata chrom start end peak 1 chr11 5291000 5291926 8 2 chr11 10988025 10988526 7 3 chr11 11767950 11768676 8 4

Could anybody give me a hint? Thanks Hermann [[alternative HTML version deleted]]

Sorry, it seems I have only replied to Lakhdar, not to the newsgroup. Below is my reply to Lakhdar, and I would like to make it more clear now, using some pseudo values for simplicity: I read bytes 1 to 124 from my encoded spx file. I decode themt and get the values: ---Frame 1---- -293 -8234 2134 17 ---Frame 2---- -9323 -732 189 2329 Both frames are just perfect as I need them. But now when I

To whom it may concern. As I would like to analyse some array data I was keen on downloading the lumi package that depends obviously on hdrcde that is not available for r 2.12.1. I did not find instructions to solve or circumvent this problem. Installing hdrcde by hand did not work either. It was not detected by > (.packages(all.available=TRUE)) if installed in the R library. Thanks Hermann

Hi there, I'm trying to remove multiple columns by name from a data.frame. As a result I need to get back the modified data.frame without the removed columns. My columns I want to delete are listed in a vector called "delete". data <- read.csv2("data.csv") delete <- c("col1", "col2", "col3") newData <- subset(data, select =

Hello, I would like to transform a character vector into a "binary" vector ("keine" and " " become 0 and the rest 1). > dput (scm) c("keine", " ", "keine", "Erstgradverw.", "Mutter", "Erstgradverw.", "Erstgradverw.", "keine", " ", "Vater",

Hi, I am stuck in a looping problem. It might be an easy problem for experienced R users but I have been unable to do it. Any kind of help or advice will be great appreciated. I am creating a spatial grid and have a list of spatial points in a folder. I can read the spatial points separately and get a count of the points in the spatial grid in R. The output should be a table showing the counts of

Hello, I have a list with gene names, fold changes (=expression level) and chromosomes. Names fold change chromosome hz 1.5 2 If I plot fold change versus chromosome (or vice versa): plot (ch, fc) I see only the chromosomes with numbers but not those with letter (x and y). What can I do? A second question: How can I add a single line in that plot at a certain

Hello, I did a pca with over 200000 snps for 340 observations (ids). If I plot the eigenvectors (called rotation in prcomp) 2,3 and 4 (e.g. plot (rotation[,2]) I see a strange "column" in my data (see attachment). I suggest it is an artefact (but of what?). Suggestion: I used prcomp this way: prcomp (mat), where mat is a matrix with the column means already substracted followed by a

Hello, having a data frame like test with pairs of characters I would like to create chains. For instance from the pairs A/B and B/I you get the vector A B I. It is like jumping from one pair to the next related pair. So for my example test you should get: A B F G H I C F I K D L M N O P > test V1 V2 1 A B 2 A F 3 A G 4 A H 5 B F 6 B I 7 C F 8 C I 9 C K 10 D L

Hello, I have start and end coordinates from different experiments (DNase hypersensitivity data) and now I would like to combine overlapping intervals. For instance (see my test data below) (2) 30-52 and (3) 49-101 are combined to 30-101. But 49-101 and 70-103 would not be combined because they are on different chromosomes (chr a and chr b). Does anybody have an idea? Thanks Hermann > df

Hi - I'm trying to verify if OpenSSH/SFTP will in fact lock files with advisory file locking in Linux. I can test locking with the linux "flock" command to verify that file locking does work - but when I upload or download a file with SFTP it will not detect a lock. I'm asking about Linux specifically because about a year ago I was doing a similar process in Solaris 9 and

Hi all, I'm writing a script that uses rsync to sync 2 dirs on C7. I noticed a strange behaviour. I have 2 dir: src and dest. In src dir I generate a testfile with "dd if=/dev/zero of=testfile bs=1M count=100" and when I run "du -h testfile" I get the correct result. Then I sync src/ to dest/ using "rsync -avS? src/ dest/", all ok but when I run "du -h

Hi, Recently I noticed file.copy() would discard the file mode information.

Hallo, I would like to use to read.xls function from the gdata package to read data from Microsoft Excel files but I experienced a problem: For example I used the following code: testfile<-read.xls("/home/.../wsjecon0603.xls", #file path header=F, dec=",", na.strings="n.a.", skip=5, sheet=2,
